2. Heat oil in a pan and add the prawns. Fry a while .That would help to keep the flavor of shrimp intact even after adding spices.Now add the whole garam masala , fry a little while now add the onion paste, ginger paste, garlic paste, chili powder, salt and little water. Cook well adding water little by little. Now add the coconut milk and cook it until the gravy reduced to half .

It will look like this;

3. In another vessel heat ghee+oil . Now add the Whole garam masala and onion.Fry until brown. Add the rice(soaked and drained). Add the ginger paste and salt ( don’t use too much salt as we have salt in the shrimp gravy too) .Fry for a while. Now add the shrimp with the gravy.Add 3 cups water ( for 2 cups of rice). Cover the lid. Careful not more than that as we have already used the gravy.Cook on medium flame.Don’t stir while cooking your polau, that would make your polau gooey and sticky.

4.When the water is almost dried out add some green chilies. Now you can stir only once with a very light hand without breaking the rice , so that the bottom must not get burnt..

5. Keep it on very low flame for another 10/15 minutes. What I do I use double-boiler system. I place my Vessel over another vessel filled with water and let it cook on the steam.It works like magic.
